Add altars for all cults and two 'test' altars to HallOfDMs ... because DMs might need to pray too.

Since HallOfDMs has unique tiles the unique file will need to be removed for this update to apply correctly. Be sure to move any stuff off the map that needs to be kept before removing the unique file.

Let's try this commit again after having to update the entire map tree thanks to Rednaxela.

Update to Zorn Castle floor two. New modified monsters and some generators added. Also mods to the floor plan. The exits to the towers and to the top floor do not yet work. This floor is basically "finished" and playable.
